Thursday June 30-1910 Grondale, Nova Scotia. Started at six a dark threatening morning and by nine a slight rain set in. Rained up to 1 P.M. A few hundred feet east of Barnes River station on the I.C.R.R. can be seen an outcrop of the Medina agnacans limestone and in the stream red sandy shales. The former is schistose with the joints vertical. The shales dip at a high angle. Farther east and to the south of the railroad along a county road may be seen a far better exposure of the Medina in close association with the complementary red (arkose) "Cambro-Siluric". Here are collected Conularia, Struthiasma bilatusis (comm.), Meristina (large and very thick Shelled), Platyceras and a Pleurotomaria. Also Cornulites flexuosus. Contact with the lower rocks was not seen although we looked all around for it. In the afternoon went to Marshy Hope and in less than one-half mile east of the station to the north of the track again saw the "Medina". Here may also be seen two beds of white quartzite, one high up on hill in the woods, the other at the edge of the hill near the road across the railway. The only fossils seen were crinoid ellumens. So far all the Siluric we have seen along the I.C.R.R. is in the Lesicaig formation and the "Medina" more of which is older than Clinton.
